[0030] The specific implementation process of the present invention is described below through multiple embodiments.
[0031] Example 1
[0032] See also Figures 1 to 4 This embodiment discloses a specific implementation of a core drilling vehicle for coal mines.
[0033] See also Figures 1 to 4 A core drilling vehicle for coal mines includes a chassis 1, a lifting assembly 2, a work platform 3 and a core drilling assembly 4 arranged on the work platform 3; the lifting assembly 2 uses the chassis 1 as a fulcrum to drive the work platform 3 to rise and fall; the core drilling assembly 4 includes a transverse track 41, a slewing mechanism 42, a drill arm support 43, a drill arm 44 and a first lifting cylinder 45; the slewing mechanism 42 drives the drill arm support 43 to swing, the slewing mechanism 42 slides along the transverse track 41, and the first lifting cylinder 45 uses the drill arm support 43 as a fulcrum to drive the drill arm 44 to rise and fall along the drill arm support 43.
[0034] Specifically, see Figures 1 to 4 In order to adapt to tunnels of different heights, this embodiment is provided with two-stage lifting. The first stage lifting is completed by the lifting component 2, and the lifting component 2 includes a connecting rod mechanism 21 and a second lifting cylinder 22. The connecting rod mechanism 21 and the second lifting cylinder 22 synchronously drive the working platform 3 to rise and fall with the chassis 1 as the fulcrum, so that the drill arm 44 has the first stage lifting; the second stage lifting is completed by the first lifting cylinder 45. The lifting stroke of the first lifting cylinder 45 is 680mm. The drill arm support 43 is provided with a lifting slide rail 431. The first lifting cylinder 45 drives the drill arm 44 to rise and fall along the lifting slide rail 431 with the drill arm support 43 as the fulcrum, so that the drill arm 44 has the second stage lifting.
[0035] See also Figures 1 to 4 In order to improve the freedom of the drill arm 44, the transverse track 41 is set at the front end of the working platform 3, and the slewing mechanism 42 is installed on the slide 421. The slide 421 moves left and right along the transverse track 41. The translation stroke of the slide 421 is 800mm, so that the drill arm 44 has the freedom of left and right translation; the rotation angle of the slewing mechanism 42 is ±90°, so that the drill arm 44 swings within the range of ±90°, and the drill arm 44 has the ability to perform coring at various angles on the entire end face of the tunnel. The drill arm 44 includes a coring drill 441 and a drill rod holder 442. The coring drill 441 is movably mounted on the drill arm 44, and the drill rod holder 442 is mounted on the top of the side of the drill arm 44. The coring rod 5 is composed of several sections. The bottom of the lowest section of the coring rod 5 is mounted on the coring drill 441, and the top is connected to the upper section of the coring rod 5. The coring drill 441 pushes the lowest section of the coring rod 5 upward to achieve coring. During the coring process, in order to maintain the stability of the drill arm 44, a number of needle-shaped columns 443 are set on the top of the drill arm 44. When coring, the needle-shaped columns 443 are inserted into the inner wall of the tunnel to stabilize the drill arm. In addition, an upward telescopic support leg 31 is set on the working platform 3. The telescopic support leg 31 can be pressed against the top of the tunnel, stabilizing the vehicle body when the drill arm 44 is working. Flip pedals 32 are respectively provided on both sides of the working platform 3 . The flip pedals 32 increase the size of the working platform 3 and facilitate the operator to stand.

The first arm 212 is hinged to one end of the base 211, and the second arm 213 is hinged to the other end of the base 211. The first end 2141 of the third arm is hinged to the first arm 212, and the second end 2142 of the third arm is hinged to the working platform 3. The third arm 214 is also hinged to the second arm 213. The pitch of the first arm 212 and the second arm 213 drives the working platform 3 to rise and fall vertically through the third arm 214. In order to ensure the stability of the working platform 3 during the lifting process, the second lifting cylinder 22 is also used to assist the working platform 3 in vertical lifting.
[0037] See also Figure 1 , the working platform 3 is at the lowest position, the distance between the working platform 3 and the roadway surface is 1050mm, the distance between the core drilling rig 441 and the roadway surface is 1400mm, that is, the lowest coring height is 1400mm; see Figure 3 The working platform 3 is at the highest position, the distance between the working platform 3 and the tunnel ground is 1750mm, and the distance between the core drilling rig 441 and the tunnel ground is 2000mm, that is, the maximum coring height is 2000mm, which has strong adaptability.
[0038] The beneficial effects of this embodiment are as follows: the working platform 3 of this embodiment has a lifting assembly 2, and the coring assembly 4 has a first lifting cylinder 45, so that the coal mine coring drill vehicle has two-stage lifting in the height direction, so as to adapt to the high-end tunnels with different end faces; the coring assembly 4 includes a transverse track 41 and a rotary mechanism 42, so that the drill arm 44 can slide left and right and can swing at ±90°, so that the drill arm 44 can drill and coring the end face of the entire tunnel, which is helpful to fully explore the coal seam information such as the direction, thickness and geological anomalies of the coal seam in various parts of the tunnel, and has strong adaptability.
